The Voidtrotter settled to the ground, still in their misty state. The same aura from before that emanated from the gem shards rose around them, swirling about before seemingly absorbing into the mist. From the same direction that the tree had fallen moments before, a chorus of howls boiled up from underneath the canopy.
A nearby tree glowed with a similar aura as the one that was emitted from the gem shards. This aura was strange-- rather than being that of a levitation spell, as the Voidtrotter originally had suspected, this aura was instead seemingly accelerating and molding the growth of the tree itself, as if it were encouraging the tree to grow according to its own specifications.
Floating back for a moment, the Voidtrotter's eyes widened as a root of unimaginable size burst from the ground, impaling a nearby hut. Luckily for the village ponies, there was nopony inside, but the structure itself was nevertheless obliterated. The same glow of magical mana then enveloped the remnants of the destroyed hut, bringing them closer to the tree itself where they were then absorbed. In the place of the hut was a single, glistening gem. A lone timberwolf now stood beside the mutated tree, almost as if it were inspecting the handiwork of the root.
Was this how the timberwolves ensured a constant supply of gems to draw from? To parasitize from those who took the stones for their own use?
It was at this time when the Voidtrotter finally turned their attention back to themselves; small sticks and twigs now surrounded them in a malformed circle, with some smaller pieces of debris violently swirling about their misty form as if they stood at the eye of a hurricane.
Though they had no body at the moment to feel the breeze, it was clear to the Voidtrotter now that a heavy wind was beginning to surround them, with larger and heavier sticks and even small branches now being pulled into the whirlwind. Piece by piece, the wooden fragments settled underneath them into what otherwise looked to be a pile of kindling, ready for a spark. It was less of a surprise now when the familiar aura of the timberwolves' gemstones surrounded the debris, pulling pieces in one by one to fit around the Voidtrotter.
It appears you are taking on the form of a timberwolf yourself, Celestia's voice mused, Perhaps it may have been your exposure to the gemstones. No matter-- just as your previous form was, this one likely will not hold for very long.
Feeling returned to the Voidtrotter's body from the ground up, starting at their new wooden paws. Bits and pieces of fine wooden chips and greenery formed the padding that returned their sense of touch-- quickly hidden away and protected by a layer of touch bark. The aura built its way up as progressively stronger and heavier twigs and sticks adhered to the Voidtrotter's new form. A dull off-green glow lit behind the Voidtrotter's new face as they opened their new eyes.
What kind of strange creature are you? the Voidtrotter could hear the Alpha timberwolf grumble, You were associated with the thieving ponies when you stumbled upon us as a winged, birdlike beast, but now you take the form of our pack. You truly are strange, intruder.
A nearby crash took the Voidtrotter's attention off their new form. A panicked stallion-- possibly even one of the farmers from before, rushed from a hut moments before another root brust through said hut, spraying debris in every direction. The tree stood still for several seconds after absorbing the remnants of the hut. A punctuated crac-ca-ca-ca-cack tore through the air, accompanied with the tree shredding itself to pieces and quickly pulling together to form yet another timberwolf. Just as with the Voidtrotter, all that remained of the hut it had decimated was a single, glistening gemstone.
The new timberwolf took a passing glance at the Voidtrotter, peering deep into their own eyes before bounding off into the underbrush.
As for the Voidtrotter, they crouched low on the ground, readying themselves to--
...Not fly, they whispered under their breath, peering over their shoulder at the notable lack of wings. I shall walk instead.
They stared at the destruction surrounding them one more time, watching as more trees mutated and collapsed in the process of the settlement's destruction. There was no doubt that the Earth Ponies would rebuild following the event, however; whether it was their strange connection to Celestia, or perhaps some deep-hidden knowledge they held, something within the Voidtrotter knew that these ponies would come to rebuild, and eventually even push back the timberwolves, coming back stronger every time.
Without another word, the Voidtrotter turned away, leaving the pandemonium behind. Perhaps they would be wrong, and the timberwolves would drive the ponies to another land, or even wipe them out entirely. There was no guarantee of what could or couldn't happen, after all-- Celestia never mentioned whether this land would serve as the setting for the future.
We are done here, Celestia's voice echoed in the Voidtrotter's head. There is nothing else that remains for you to experience within this realm.
The land warped beneath the Voidtrotter's paws, undulating in waves before flattening out and fading away, leaving behind once again the Void.
As usual, this is where the story leaves off. We'll wipe the slate clean, leaving only the Timberwolf form of the Voidtrotter while everything else is once again determined by you, the readers of the story.
